A strategy used to build bodily
mass, in which
one holds in his/her feces in to increase the productivity from a workout. The goal of shitmaxxing is to hold your feces in until you'
re at least finished with your workout. The longer
one holds his/her shit in, the larger the gains. The
basic theory behind shitmaxxing is that the uncomfortable feeling caused by holding your feces in incites a flight or fight reaction, leading to an increase in testosterone and adrenaline production. This in turn leads to more reps, more sets, longer sessions and more gains.
